Multiplus, Multifunctional, with intelligent power management

The Victron MultiPlus Inverter Charger is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology, and a high-speed AC transfer switch in a single compact enclosure. Next, to these primary functions, the MultiPlus has several advanced features, as outlined below.

Two AC Outputs

The main output has no-break functionality. The Victron MultiPlus Inverter Charger takes over the supply to the connected loads in the event of a grid failure or when shore-/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on the input of the MultiPlus. Loads that should not discharge the battery, like a water heater, for example, can be connected to this output (second output available on models rated at 3kVA and more).

Virtually unlimited power thanks to parallel operation

Up to six Multis can operate in parallel to achieve higher power output. Six 24/3000/70 units, for example, provide 15kW / 18kVA output power with 420 Amps of charging capacity.

Three phase capability

In addition to parallel connection, three units can be configured for three-phase output. But that’s not all: with three strings of six parallel units a 45 kW / 54 kVA three-phase inverter and 1260 A charger can be built.

Split phase options

Two units can be stacked to provide 120-0-120 V, and additional units can be paralleled up to a total of 6 units per phase, to supply up to 30 kW / 36 kVA of split phase power. Alternatively, a split phase AC source can be obtained by connecting our autotransformer (see data sheet on www.victronenergy.com) to a ‘European’ inverter programmed to supply 240 V / 60 Hz.

PowerControl – Dealing with limited generator, shoreside or grid power

The Victron MultiPlus is a very powerful battery charger. It will, therefore, draw a lot of current from the generator or shore side supply (nearly 20 A per 3 kVA MultiPlus at 120 VAC). With the Multi Control Panel a maximum generator or shore current can be set. The MultiPlus will then take account of other AC loads and use whatever is extra for charging, thus preventing the generator or shore supply from being overloaded.

PowerAssist – Boosting the capacity of shore or generator power

This feature takes the principle of PowerControl to a further dimension. It allows the MultiPlus to supplement the capacity of the alternative source. Where peak power is so often required only for a limited period, the MultiPlus will make sure that insufficient shore or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery.

Four stage adaptive charger and dual bank battery charging

The main output provides a powerful charge to the battery system by means of advanced ‘adaptive charge’ software. The software fine-tunes the three-stage automatic process to suit the condition of the battery, and adds a fourth stage for long periods of float charging. The adaptive charge process is described in more detail on the Phoenix Charger datasheet and on our website, under Technical Information. In addition to this, the Victron MultiPlus will charge a second battery using an independent trickle charge output intended for a main engine or generator starter battery.

System configuring has never been easier

After installation, the MultiPlus is ready to go. If settings have to be changed, this can be done in a matter of minutes with a DIP switch setting procedure. Even parallel and 3-phase operation can be programmed with DIP switches: no computer needed! Alternatively, VE.Net can be used instead of the DIP switches. And sophisticated software (VE.Bus Quick Configure and VE.Bus System Configurator) is available to configure several new, advanced, features.

Features

• Customizable status LED bar with RGB breathing lights.
• Built-in Wi-Fi for mobile monitoring (Android/iOS App is available).
• Supports USB On-the-Go function.

SinusMax – Superior engineering
Developed for professional duty, the Phoenix range of inverters is suitable for the widest range of applications.
The design criteria have been to produce a true sine wave inverter with optimised efficiency but without
compromise in performance. Employing hybrid HF technology, the result is a top quality product with compact
dimensions, light in weight and capable of supplying power, problem-free, to any load.

Extra start-up power
A unique feature of the SinusMax technology is very high start-up power. Conventional high frequency
technology does not offer such extreme performance. Phoenix inverters, however, are well suited to power up
difficult loads such as refrigeration compressors, electric motors and similar appliances.

Virtually unlimited power thanks to parallel and 3-phase operation capability
Up to 6 units inverters can operate in parallel to achieve higher power output. Six 24/5000 units, for example,
will provide 24kW / 30kVA output power. Operation in 3-phase configuration is also possible.

To transfer the load to another AC source: the automatic transfer switch
If an automatic transfer switch is required we recommend using the MultiPlus inverter/charger instead. The
switch is included in these products and the charger function of the MultiPlus can be disabled. Computers and
other electronic equipment will continue to operate without disruption because the MultiPlus features a very
short switchover time (less than 20 milliseconds).

Computer interface
All models have a RS-485 port. All you need to connect to your PC is our MK2 interface (see under accessories).
This interface takes care of galvanic isolation between the inverter and the computer, and converts from RS-485
to RS-232. A RS-232 to USB conversion cable is also available. Together with our VEConfigure software, which
can be downloaded free of charge from our website, all parameters of the inverters can be customised. This
includes output voltage and frequency, over and under voltage settings and programming the relay. This relay
can for example be used to signal several alarm conditions, or to start a generator. The inverters can also be
connected to VENet, the new power control network of Victron Energy, or to other computerised monitoring
and control systems.

New applications of high power inverters
The possibilities of paralleled high power inverters are truly amazing. For ideas, examples and battery capacity
calculations please refer to our book “Energy Unlimited” (available free of charge from Victron Energy and
downloadable from www.victronenergy.com

L051100-A Energy Storage System is consisted of 2 sets of M025100-A modules manufactured by

Sunsynk. In each M025100-A, there are 8 pcs of 100 Ah LFP cell originated from CATL. The overall

system also provides standard communication port, i.e. CAN and RS485, to monitor the working status

and communicate with upper machine as well as the Power Conversion System (PCS) in front.
